The Gunners skipper missed out against Cardiff on Tuesday night after he suffered a nasty facial injury during the FA Cup game with Manchester United.

Koscielny was accidentally kicked in the face by Romelu Lukaku and there were fears that he had fractured his jaw.

Fortunately that was not the case, but he did have to undergo surgery at the weekend as a result of the incident.

"When the incident with Lukaku happened, I really thought my jaw was broken," Koscielny explained. "It was so painful.

"I went to the hospital and after some tests and X-rays, it showed that thankfully it wasn’t. I was relieved, but I still needed some surgery on Saturday to take out all the blood clots created by the impact."
